There is a difference between cognitive decline and just being a racist piece of shit.

"Beat medicaid" was cognitive decline. That wasn't a misspeak. His brain was mash potatoes that entire debate. That was just the funniest one. The really pathetic "sad slow confused old man" one's aren't as memorable.

Trump saying "eating cats and dogs" is literally just him being a racist piece of shit. That wasn't cognitive decline. Unless you think JD vance is showing old age cognitive decline.

Having said all that. They are both racist old white men with signs of dementia. The counter example you gave is just not a good example for Trump.
